I want to raise an issue I saw in China. Some people invented a way of washing crayfish (and increasingly crabs too) using an ultrasonic bath. As you can see here (and here), the animals show fierce escape behavior as soon as the ultrasonic is turned on, and they try to stay away from the water when there is ultrasonic passing through, but they have to stay in the bath for 2-5 minutes. Seems extremely inhumane if these animals feel pain.

Wow that seems very bad
